Tailored to Make Your VPS Faster

cPanel® & WHM® VPS Optimized Automatically Reduces Memory Consumption on Virtual Servers

What is VPS Optimized?

VPS Optimized is a version of cPanel available for use to customers whom purchase a VPS license. With cPanel’s VPS Optimized, you receive the same features and functionality as cPanel. VPS Optimized allows you to run cPanel software smoothly within the memory constraints of a VPS.

Why VPS Optimized?

VPS’s usually have RAM contraints. VPS Optimized was designed solely for the installation of VPS’s. It maintains the same functionality as cPanel but has simply been optimized to easily and successfully operate within the constraints of a VPS environment.

Testing Results

cPanel VPS Optimized has been tested specifically on VPS instances with low amounts of total memory. Baseline memory usage numbers were significantly reduced by updating a VPS from cPanel / WHM® to cPanel VPS Optimized with no other changes. Baseline memory usage numbers are provided below.

Compatible Software

VPS Optimized is designed for installation on these VPS machines:

Supported Virtual Environments [1] [2]
Microsoft Server® 2008 Hyper-V [3]
OpenVZ (stable releases only)
Oracle VM VirtualBox, VirtualBox OSE
VMware® Server, VMware® ESX Server
Xen, XenEnterprise™, XenExpress™, XenServer™

It boasts a 12-15 Megabyte reduction in standing memory usage. Add that to the nearly 60% memory usage reduction from previous versions. This is accomplished while retaining all functionality of a regular cPanel/WHM installation.

Additional improvements include a redesigned log processing daemon that reduces memory utilization, and a process monitoring daemon that includes service-specific verification. The third layer of performance enhancing features focuses on DNS clustering with the syncing process and error detection.

Deployment of the Optimized version is available with cPanel and WHM 11.24. When 11.24 is installed or updated these enhancements are automatically applied and immediately available.


cPanel VPS Optimized is available through cPanel Partner NOC’s and direct from cPanel.
